After reviving its cult favorite Szechuan sauce for a single day last year, fast-food giant McDonald's is bringing it back in greater quantities and availability starting this Monday.

McDonald's promises to have 20 million cups of the teriyaki sauce to give away with qualifying purchases at all its locations nationwide. That's a marked change from Oct. 7, 2017, which saw a limited number of the sauce cups distributed at only a handful of "select" stores. (The Indianapolis area was limited to just one participating location, the McDonald's on Broad Ripple Avenue.)

"Our super-limited batch, though well-intentioned, clearly wasn’t near enough to meet that demand," McDonald's wrote on WeWantTheSauce.com, a website created for this promotion. "We disappointed fans and we are sorry."

Szechuan Sauce returns 2/26! 20 MILLION CUPS spread across all US McD's!

McDonald's says the promotion will last "while supplies last." If divided evenly, each of the approximately 14,000 restaurants in the U.S. will receive about 1,400 cups of the sauce. However, it won't work like that in reality: Stores with higher traffic and sales will get more cups, while smaller stores will get fewer.

Introduced in 1998 as part of a promotion for Disney's "Mulan" and discontinued later that year, McDonald's Szechuan sauce returned to the public eye when it became a plot point in a 2017 episode of Adult Swim's "Rick & Morty."
